STRAW-SHAKEB.

Specificationof Letters Patent No. 20,976,2dated July 20, 1858.

To'all whom it may concern: rated so as to allow the introduction of the Be it known that I, LEONARD ELLIG, a I pin (Qand 8) in drawings, Figs. II: and III. resident ofMill Creek, Pennsylvania, have will now describe the nature andpracinvented a new and useful Improvement in tical operations of the above described Straw-Shakers, of which the following is a shaker, as far as may be deemed necessary, description. with its uses and advantages over other Figure I, is a perspective view of my shakers. shaker.

Letter (6), is a strap rated from the straw before it leaves the thrown over the pulley and attached to any shaker, therefore it will require no other threshing machine not shown in the drawcomplex arrangement to separate the grain ings. Letter (cl) represents an articulation because the inclination of the shaker alone of the shaft (12) to the movable bottom (w) will accomplish the result of a clean separaby means of a pin (a) passing through the tion. In suspending my shaker as above I folds of, a scroll and eye of the pitman (Z) have also an advantage over other shakers, by reason whereof I can convey the straw into a straw-mow or any other place which otherwise might require one or more indi- In susshown at (f, f) Figs.

Another advantage gained on the inboards (m, m) and on opposite sides of the cline principle consists in this, that the feeder behind the threshing machine, by

same in like manner. These arcs are perforeason of the inclination can see through the slide cap (a) into the shaker and thereby be able to detect any irregularity of the shaker which often occurs by feeding too fast or by other accidents.

The spring sustains the important office of assisting the crank (1 over the center of motion by its action and reaction resting on the hollow, movable cylinder (f).

The crank (P) on axle (R) with its appendent shaft (4%) gives motion to the shaker, and the arms (4: and 5) on both sides, while they hold the movable bottom (w) suspended are free to move in a forward or retreating direction, governed alone by the motion of the crank, which is designed to effect a rotary-projectile-motion forward, whereby the straw is pitched forward and runs up the incline surface of the movable bottom The tongue (0) is designed to rest against the crank and propelled thereto by means of a wedge (0) in order to keep the crank always at its official place.

The pulley (s) is a fixed pulley and by means of a strap by which it is attached to any threshing machine, puts the crank in motion.

What I describe as arcs (7 7') perforated with holes as shown in the drawings, serve the uses of hanging my shaker at any angle I desire; because when the straw is somewhat green, or damp and therefore heavy the shaker must be less inclined, otherwise more inclined, which is done by shifting the pins in the holes of the arcs as seen at (7, 7).

My shaker may be separated for the convenience of storage, by lifting the bolts or taking out the screws at (j) on both sides and the pin (a) that passes through the eye of the pitman (Z) which is a simple process, and needs no minute description.

What I claim as my improvement and desire to secure by Letters Patent of the United States, is

1. The movable bottom (w) in combination with the arms (I and 5) and spring (79,) as set forth in the specification.

2. The movable cap (a) adjusted as described and for the purpose set forth.
